Used to use MS OneNote, switched to using Outline (Mac) when I moved away from Windows. I'm still pretty happy with it, but I'm a one-device-at-a-time, laptops-are-as-mobile-as-I-go kind of guy who doesn't care about syncing, etc. However, most of the time I just use paper. I generally use 200-ish page hardbound books with a narrow rule, and go through around 2 a year with work; entries are dated, volumes are dated when filled and filed away. I don't treat them with the full rigor that you would a real "lab notebook", but it's the same general idea. For hobby use, I use similar books, but usually blank or graph lined. For day-to-day reminders and such, I'm almost always carrying a little 50-cent spiral-bound notebook. When used up, remove the spring, toss the pages and cover into the recycle bin. My use of software for note taking at this point is pretty much confined to initial research where I'm more interested in saving images and URLs than any actual details that might end up on paper later.
